Hello,
Here is the example code:
DATA What;
IF _N_=1 THEN DO;
DO I=1 TO abc;
SET sashelp.class POINT=I NOBS=abc;
x=i;
*output;
END;
END;
RUN;
Pleae helpe me explain _n_=1 and point= here.
Thanks!
Thanks!
_n_ is an automatic variable for the input line (simplified). So the If _n_=1 is "do this only once at the beginning"
Point refers to a specific observation in a data set. This so you can read a specific (hopefully you know why you want that observation) observation into the working data vector.
Nobs creates a temporary variable (in this case ABC) with the number of observations in the data set sashelp.class.
